Salt May Be Bad for More Than Your Blood Pressure

Study found damage to organs and tissues, even with no sign of hypertension

Even if you don’t develop high blood pressure from eating too much salt, you may still be damaging your blood vessels, heart, kidneys and brain, a new study warns.

Researchers reviewed available evidence and found that high levels of salt consumption have harmful effects on a number of organs and tissues, even in people who are “salt-resistant,” which means their salt intake does not affect their blood pressure.

High salt consumption levels can lead to reduced function of the endothelium, which is the inner lining of blood vessels. Endothelial cells are involved in a number of processes, including blood clotting and immune function. High salt levels can also increase artery stiffness, the researchers said.

“High dietary sodium can also lead to left ventricular hypertrophy, or enlargement of the muscle tissue that makes up the wall of the heart’s main pumping chamber,” said study co-author David Edwards. He is an associate professor in kinesiology and applied physiology at the University of Delaware.

“As the walls of the chamber grow thicker, they become less compliant and eventually are unable to pump as forcefully as a healthy heart,” he explained in a university news release.
